PROBLEM TO BE SOLVED: To provide an inkjet head unit of which the bonded section between a flexible circuit board and an inkjet head is hardly peeled. SOLUTION: This inkjet head unit 1 consists of the inkjet head 10 and the band shaped flexible circuit board 13, and one end of the flexible circuit board 13 is connected to the inkjet head 10 so as to cover an upper face of a piezoelectric actuator 12 of the inkjet head 10. The flexible circuit board 13 is raised from the portion bonded with the piezoelectric actuator 12 by being bent and the other end is connected to a relay circuit board. A rigid member 20 is provided to a portion on the flexible circuit board 13 where the piezoelectric actuator 12 is overlapped. The rigid member 20 is provided to protrude to the side of the circuit board rather than a position corresponding to a bonded section of a terminal 39 with a terminal land 60.
